Here’s a shining example of a perverse incentive if ever there was one.

When my phone’s battery is dying, my phone decides to alert me by leaping into life and bleeping loudly whilst lighting up the big LED screen with a warning that my battery is low.

Yeah, that helps.

This warning then keeps the screen brightly lit until I acknowledge it by pressing the ‘OK’ button.  Even then, it doesn’t switch to standby until I do it myself.

It’s like shouting “You’re being very quiet and stealthy!” to a ninja, mid-creep.

He knows.  And now he isn’t.

Oh look, my battery has drained drastically in the last 2 minutes for some reason.

Oh look, the ninja has been stabbed through the face by the palace guards.
